The attacks come against the backdrop of the more than two-month war between US ally Israel and the Iran-backed Palestinian Islamist militant group Hamas in the Gaza Strip.

In a statement, the US embassy said “two salvoes of rockets” were fired at the mission compound at around 4.15am (0115 GMT).

“Indications are the attacks were initiated by Iran-aligned militias,” said a US spokesperson.

“We again call on the government of Iraq… to do all in its power to protect diplomatic and coalition partner personnel and facilities.

“We reiterate that we reserve the right to self-defence and to protect our personnel anywhere in the world,” the spokesperson added.

Since mid-October, there have been dozens of rocket or drone strikes by pro-Iran groups against US or coalition forces in Iraq as well as in Syria.

But Friday’s rocket attack was the first against the US embassy in Baghdad since the Israel-Hamas war began on October 7, raising regional tensions and fears of a wider conflict.

An Iraqi security official said “Three Katyusha rockets targeting the American embassy fell close to the Green Zone,” near the river Tigris. They spoke on condition of anonymity as they were not authorised to speak to the media.

There are roughly 2,500 US troops in Iraq and about 900 in Syria as part of efforts to prevent a resurgence of the Islamic State group.
